Impossible de charger le runtime natif TensorFlow. Raison: Image non trouvée. Qu'est-ce que je fais mal?

Fonctionnant sur un Macbook Pro avec un I7 quad core et le NVIDIA GeForce GT 650M.

Je reçois ce message d'erreur lors de l'exécution de Tensorflow à partir de virtualenv. Qu'est-ce que je fais mal? J'utilise la version 3.2.0 de protobuf

Merci pour toutes vos suggestions. J'ai essayé d'installer la seule version CPU de TensorFlow en utilisant 

{
pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-1.0.1-py2-none-any.whl
}

qui a résolu le problème. La chose intéressante était les messages indiquant que je n'utilisais pas le GPU.

Mais cela a tendance à être:

Je télécharge donc setuptools-0.6c11-py2.7.Egg à partir de https://pypi.python.org/pypi/setuptools/0.6c11 .__ et cela fonctionne enfin.
